Lindsay Lohan celebrated her 22nd birthday party at Teddy’s restaurant, on July 2. Her best friend, Samantha Ronson, shared the spotlight with her. She looked really happy as previously, she had wanted to look for sponsors for her birthday party but that idea was scrapped due to insufficient response. Poor Lindsay. Her Dad Michael sprang a surprise with the warning of an unexpected half sister. He is waiting for the results of DNA paternity test to prove that he is the father of Ashley Kaufmann.
